The Gist
The author argues that when politicians say the rich should pay their 'fair share,' it's an empty slogan because nobody ever says what number would actually be fair. He warns that this vague rhetoric is being used to justify piling on more and more taxes—on investment gains, wealth, inheritances, and through sneaky small surtaxes—even though the wealthy already pay the bulk of federal income taxes.
Conclusion
Politicians' calls for the wealthy to pay their 'fair share' are meaningless as tax policy because no one defines what percentage or amount would actually constitute 'fair,' and this vague rhetoric is being used to justify an ever-expanding array of tax increases on high earners.
Premises
- The top 1% of taxpayers already pay roughly 40% of federal individual income taxes, and the top 10% pay the overwhelming majority of taxes, suggesting the wealthy already contribute disproportionately.
- Politicians who invoke 'fair share' never specify a concrete percentage or dollar amount that would satisfy the standard, making the phrase impossible to evaluate or achieve.
- Beyond ordinary income tax rate hikes, there are at least four additional mechanisms (capital gains tax increases, wealth taxes on unrealized assets, estate tax hikes, and stacking 'small' surtaxes) that politicians are pursuing to extract more revenue from the wealthy.
- Taxing unrealized wealth or capital gains ignores practical realities, such as illiquidity (e.g., a business worth $100 million on paper without corresponding cash) and behavioral responses from investors who take on risk expecting a return.
- The same dollar of income can be taxed multiple times across a person's life and after death (income tax, capital gains tax, estate tax), raising the question of how many times taxation is fair.
- Small incremental surtaxes (e.g., 3.8% NIIT, 0.9% Medicare tax, state millionaire surtaxes) accumulate into substantial additional tax burdens even though each appears minor individually.
- If lawmakers object to loopholes or provisions in the tax code, the proper remedy is to change the law through Congress, not to vilify taxpayers who are legally following the rules Congress itself created.
Assumptions
- The current tax burden distribution (top 1% paying ~40% of income taxes) is itself evidence that the wealthy are already paying a fair or sufficient amount, rather than being consistent with a highly unequal income/wealth distribution.
- Politicians pushing 'fair share' rhetoric are acting in bad faith or without genuine policy reasoning, rather than having implicit or evolving standards of fairness tied to specific budgetary or equity goals.
- Raising capital gains, wealth, or estate taxes will necessarily produce significant negative behavioral changes (reduced investment, capital flight) severe enough to outweigh potential revenue or equity benefits.
- Taxing wealth or gains multiple times (income, capital gains, estate) is inherently unfair, rather than a legitimate way to tax different economic events (earning, growth, transfer) that occur at different times.
- The absence of a single, universally agreed-upon numerical definition of 'fair share' invalidates the entire policy debate, rather than being a normal feature of political and moral disagreement about taxation.
